#codeigniter $this->input->post();

Question

我正在做一个更新用户数据的简单表单。我制作了一个带有隐藏输入的表单，用于将用户发送到表单，直到这里一切正常，我可以找到我的 $this->input->post('userid'); 现在在论坛中还有另一个隐藏输入 name="userid" 但是当我提交表单时我丢失了它。这是一个非常愚蠢的东西，但我要疯了。有的可以帮忙吗？谢谢

这里 $this->input->post('userid') 有效，但数据更新后，表单为空。 也许我的英语太糟糕了，也许电脑可以帮助解释这个问题 before submit

after submit

Answer 1

表单中的两个输入不能具有相同的名称，除非名称在数组中。所以，总是选择第一个输入值。
